When going back through the undo history, floating plugin windows will often pop up on the screen, obscuring view of the Arrangement. They don't disappear when you Redo, but they do create a new undo point if you close them.
Would really appreciate an option for floating plugin windows to be ignored by Undo altogether. Currently it can often be impossible to see what's happening with each undo, since the main window is covered by floating windows...
